Step 1: Definition of autobiography.
An autobiography is a self-written account of one's life, combining personal experience, confession, and reflection.
Step 2: Historical development.
- St. Augustine's Confessions (4th–5th century) is regarded as the earliest major example of Western autobiography. It combines spiritual reflection with personal narrative, setting the template for later works.
- Joyce's Portrait is a 20th-century modernist autobiographical novel, not a forerunner.
- Wordsworth's The Prelude is a Romantic autobiographical poem, but it comes much later.
- Walton's Lives are biographies of others, not an autobiography.
